Overview
- Summary of dataset and variables
The number of casualties in police-recorded road collisions by speed limit, type of vehicle, severity, date and area.
- Data collection or calculation
The police compile statistical data about road traffic accidents and casualties (called Stats19 data) for the Welsh Government and the Department for Transport (DfT). This follows police attendance at accidents that involve any personal injury, together with members of the public reporting personal injury accidents directly to the police. The figures are based on information available to the Welsh Government 14 weeks after the end of the latest quarter. The Stats19 data are a set of numeric and alphabet characters. A casualty is defined as, a person killed or injured in an accident. One accident may give rise to several casualties. Casualties and accidents are subdivided into killed, seriously injured and slightly injured categories. Casualties reported as killed include only those cases where death occurs in less than 30 days as a result of the accident. They do not include those who died as a result of natural causes (e.g. heart attack) rather than as a result of the accident, nor do they include confirmed suicides.
- Statistical quality
The figures in this dataset show the severity of a casualty's injuries as reported by the police officer that recorded the collision. These unadjusted severities are not consistent across different recording methods and care should be taken when comparing the number of serious or slight casualties over time or between police force areas. Dyfed-Powys Police adopted an improved injury-based reporting system in May 2023 and South Wales Police adopted it in November 2025. North Wales Police and Gwent Police have not yet changed their reporting system. In future releases we will publish figures using adjusted severities. These adjusted figures can reliably be used to compare trends over time across the country. As South Wales Police have only adopted the new reporting system recently, adjusted figures are currently too volatile to be meaningful at the level of detail presented in this dataset. We describe the changes to how injury severity is recorded by police forces across Great Britain in our Chief Statistician's blog understanding road collision and casualty statistics. To assist users with what this change means, we have recently published a further Chief Statistician’s update explaining these changes, their impacts and the adjustments needed to severity data.
The figures shown may change in future if there are late amendments. Similarly, the figures for earlier years may differ from those previously published. The figures cover only road accidents reported to the police involving personal injury. This data is obtained from administrative sources and thus may be affected by changes in procedures within those systems. There is some possibility of under-reporting and under-recording as well as for the misclassification of accidents though these are minimised by local authorities and the Welsh Government conducting a number of data validations. For example, Welsh Government data analysts may query the location of an accident with a police force when the grid reference of an accident is in a different local authority to the one specified in the data return. These issues are discussed in more detail in a Statistical Article ‘Quality Report for Welsh Road Casualties’. This article also summarises the sources and methods used to compile the road accident and casualty figures for Wales. It also reviews the quality of the resulting figures in terms of the six dimensions of statistical quality of the European Statistical System. The aim is to provide background information about road casualty statistics for Wales in a single document for all users of the published statistics.
